Oh, another thought here. I am turning circles myself and am getting some head spins.

Now it is almost a 2m version!!! Only J4 is still a 2SK170 without R15, and 2n3819 is there instead of 3k3. All others are 2m version.

Just check that 2n3819 has an Idss = 2 - 20mA.

Should I swap the 2n3819 with a 3k3 resistor? No brainer or getting into a new territory?

P.S. Ha, Ha! I cannot escape the duty of a tester again, as it is now almost a 5m.

Yes, use the resistor, less prone to oscillate.
